Hey guy's I ned your help. I need a carb. and a guy at work said he had a 850 mighty Demon. It is new and he just never used it. The price is pretty cheap but I think I need a 750. What do you think?
My motor is a 396 bored .060, Edelbrock air gap, ls-6 heads ported, 294 comp extreme cam, msd ign., 373 gears. I like to drive my cars so if it is too much for driving let me know.

Thanks Brent

I'm thinking that the 750 on my 396 is a little too large.

I've got the same setup 396, ported iron heads, 292H with an old torker II manifold. i had the carb heavily modified to get the idle right and the performance where i wanted it.
